Sealing layer of organic EL device

Abstract

Provided is an organic EL device which can prevent invasion of moisture to an organic EL element. The organic EL device has an organic EL element in which a first electrode layer, a functional layer, and a second electrode layer are stacked in sequence on a transparent substrate having a planar expanse, and an inorganic sealing layer for sealing at least an emission area of the organic EL element. A soft adhesion layer is stacked directly onto the inorganic sealing layer with a planar expanse, and the soft adhesion layer is made of a resin, and has flexibility.

The invention claimed is: 
     
       1. An organic EL device having a sectional structure including a laminate having a first electrode layer, an organic light emitting layer and a second electrode layer on a base member, and a sealing layer that seals the whole or part of the laminate, wherein
 a buffer layer is stacked directly or indirectly with respect to the sealing layer, 
 the buffer layer is a soft resin layer made of a resin, having flexibility, 
 an emission area that actually emits light and a feeding area to which a feeding member is connected exist when the base member is planarly viewed, 
 the organic EL device has a hard wall part surrounding an area including the emission area, and at least part of the feeding member is embedded in the hard wall part, 
 electricity is fed to the feeding area from outside via the embedded feeding member, 
 the organic EL device further has a conductive base member having electric conductivity on the second electrode layer, 
 the conductive base member and the feeding area are electrically connected with each other via the feeding member, and 
 in the emission area, electricity is fed from the outside via the conductive base member. 
 
     
     
       2. The organic EL device according to  claim 1 , wherein the conductive base member is bonded by the soft resin layer. 
     
     
       3. The organic EL device according to  claim 1 , wherein the feeding member is arranged to stretch from the feeding area to the emission area. 
     
     
       4. The organic EL device according to  claim 1 , wherein the hard wall part is a hard resin layer formed of a hard resin having an insulating property, and covers part of the conductive base member. 
     
     
       5. The organic EL device according to  claim 1 , wherein the feeding member is a bonding wire. 
     
     
       6. The organic EL device according to  claim 1 , wherein the feeding member is wholly embedded in the hard wall part.
